Buckeye 10" Fusible Link Bracket Kit, Single Item - FLB-1

The Buckeye 10" Fusible Link Bracket Kit (FLB-1) is a mission-critical hardware assembly engineered to serve as the structural anchor for the Buckeye Kitchen Mister fire suppression system. In the sophisticated architecture of a commercial kitchen, the detection line serves as the thermal nervous system. While the agent cylinders provide the muscle, the FLB-1 ensures the system possesses the sensory detection accuracy required to actuate the moment a thermal event is identified.

For contractors and facility managers, the FLB-1 is more than a simple bracket; it is a UL 300 listed component that eliminates the variables of field-fabricated mounting. By utilizing a 10-inch high-profile stand-off design, this bracket ensures that the fusible link is suspended precisely in the path of potential fire plumes, isolated from the cooler metal surfaces of the hood plenum. Utilizing the genuine FLB-1 kit ensures your facility maintains its safety listing and provides the zero-lag thermal response necessary to stop a grease fire before it reaches the exhaust ductwork.

Mitigating the Heat Sink Effect

If a link is mounted flush against the hood's interior wall, the massive thermal mass of the stainless steel hood draws energy away from the detector, creating thermal lag. By extending the link 10 inches away from the surface, the FLB-1 removes the detector from the hood's thermal boundary layer, allowing the link to reach its activation temperature based on the air temperature of the plume rather than the temperature of the hood's metal.

Thermal Plume Centering

In a fire event, hot air and grease vapors rise in a focused plume with the highest temperatures concentrated at the center. The 10-inch stand-off distance is strategically calculated to place the fusible link directly in this high-energy stream, ensuring the system reacts to the actual hazard, a critical factor for high-BTU appliance monitoring.

RTI Optimization via Higher Air Velocity

Because the FLB-1 positions the link in the higher-velocity air of the exhaust stream, it increases the convective heat transfer rate, speeding up the time it takes for the link to melt and ensuring the fastest possible mechanical detection trigger.

Kit Contents

The FLB-1 is a pre-packaged detection hardware assembly for 1/2" EMT conduit detection lines. The kit includes the 10-inch heavy-gauge zinc-plated steel bracket, dual 1/2" EMT conduit connectors, copper/zinc cable crimps to create permanent stops on the 1/16" stainless steel cable, and stainless steel S-hooks that facilitate instant cable drop when the link melts.

Plenum Geometry Centering

The FLB-1 must be mounted so the link is centered over the appliance hazard zone. If a range is moved or a new fryer is added, the FLB-1 must be relocated to ensure the link remains in the primary thermal plume path.

The 6-Month Friction Audit

During semi-annual inspections, technicians must verify that the 1/16" cable moves freely through the connectors. If grease has solidified inside, it can create friction resistance that holds the cable even after the link has melted.

Supervised Tension Verification

The FLB-1 is designed to handle the mechanical tension required by the Buckeye Mechanical Release Module (MRM). Technicians should verify the bracket is not flexing under load; a flexing bracket indicates a structural mounting failure.

Avoiding Heat Shielding

Ensure that no kitchen equipment is positioned between the cooking surface and the FLB-1. Any obstruction can shield the link from rising heat, effectively blinding the BFR series detection system.

Does the FLB-1 include the fusible link?

No. Fusible links are temperature-specific and must be ordered separately to match the specific appliance below the bracket. The FLB-1 is the universal housing for these links.

Why is it called a "High-Profile" bracket?

"High-Profile" refers to the distance the bracket holds the link away from the hood surface. The 10-inch stand-off distance is the preferred choice for high-heat appliances where the plume is wider and more intense.

Can I use this bracket with an Ansul R-102 system?

While the mechanical concept is similar, the Buckeye FLB-1 is specifically listed for use with the Buckeye Kitchen Mister. Mixing manufacturers' detection hardware is a code violation.
